Aluminium rectangular profile with reinforcing ribs offers high stability and a secure hold during use. Integrated anti-slip stoppers ensure a firm hold when marking and prevent the spirit level from slipping. The Stabila mounting technology guarantees long-term precision, with a measuring accuracy of ± 0.5 mm/m in the normal position and ± 0.75 mm/m in the folded position. Quality vials ensure optimum readability and are made of highly transparent, resistant acrylic glass with precisely ground inner contours and fluorescent vial fluid. The spirit level has two measuring surfaces for precise measurement in all positions. Coated measuring surfaces protect sensitive areas, while plastic end caps protect the profile from knocks. The electrostatic powder coating makes cleaning easier. This product is particularly suitable for gardening and landscaping, reinforced concrete construction, joinery work and tiling.
